MPs Properties, Classification, Characterization, Sources, Environmental and Health Impact
AI summary Read the abstract
Researchers provide a comprehensive overview of microplastic properties, classification systems, characterization methods, and environmental sources, tracing how increasing plastic consumption and waste generation drives the accumulation of these diverse pollutants across land, water, and living organisms.
The increased use of diverse plastic products that results from high living standards and a modern way of life eventually leads to a rise in the production of plastic garbage in the environment. Microplastics (MPs) are a broad group of pollutants with a variety of...

Detection, characteristics, and some influencing factors of MPs in rainfall
AI summary Read the abstract
This systematic review synthesized global evidence that microplastics are transported through the troposphere and deposited via rainfall even in remote regions, with PET, polypropylene, polyamide, and polyethylene as the dominant polymers found in rainwater, and meteorological factors controlling variability. The findings confirm that atmospheric transport and precipitation represent a major dispersal vector for microplastics, meaning contamination of soils, drinking water sources, and human food systems is partly driven by weather patterns.
Ecotoxicological Effects of MPs as Emerging Micropollutants: Examination of Biomarkers, Current State, and Future Perspectives
AI summary Read the abstract
Researchers examined the ecotoxicological effects of microplastics as emerging micropollutants, reviewing biomarker responses across terrestrial and aquatic organisms and highlighting how combined environmental stressors amplify the harm microplastics pose to biodiversity and ecosystem function.
Abundance and Characterization of MPs in Composts Produced in Mazandaran, Iran
AI summary Read the abstract
A cross-sectional study of three compost factories in Mazandaran, Iran found a mean microplastic concentration of 16,981 items per kilogram, with fibers comprising 75% of particles and polyurethane, polyamide, and LDPE among the identified polymers. Compost derived from municipal solid waste is a significant and underappreciated vehicle for introducing microplastics into agricultural soils, contaminating land that grows food for human consumption.
Case Study—Risks Posed by MPs Presence and Transport in Brisbane River Sediments, Australia
AI summary Read the abstract
This case study characterized the environmental risk and transport behavior of microplastics in urban river sediments collected from 22 sites along the Brisbane River in Australia, analyzing how sediment dynamics move plastic particles through the watershed. Urban river sediments act as both sinks and secondary sources of microplastic contamination, threatening downstream aquatic life and water quality used for human consumption.
Applications of Membrane Bioreactors for Wastewater Treatment: MPs Removal, Mechanisms and Future Perspectives
AI summary Read the abstract
Researchers reviewed how membrane bioreactor technology can remove microplastics from wastewater far more effectively than conventional treatment plants, potentially preventing millions of plastic particles per day from being discharged into rivers and oceans.
